Question

x+1 ,x+2 ,x-1 ,x+3 ,x-2 when x belongs N if the median of the data is 12 then value of x is

Answer 1

observations=5 odd
N(median) =(number of observations+1/2) th term
=(5+1/2)th term
=6/2= 3rd term
that is x-1
ATQ
median=x-1
12=x-1
x=12+1
x=13

pls mark it as brainliest answer and thank you

Answer 2

The value of x is 11

Step-by-step explanation:

Data : x+1 ,x+2 ,x-1 ,x+3 ,x-2

Arrange the data in ascending order

x-2,x-1,x+1,x+2,x+3

No. of observations = 5 = odd

So, median =$\frac{n+1}{2}\text{th term}=\frac{5+1}{2}$=3 rd term = x+1

We are given that the median is 12

So, x+1=12

x=11

Hence The value of x is 11
